Abstract (en)
[origin: EP1946864A1] The method involves detecting a path covered by a moveable punch (10) during a punch rivet process by using a travel sensor. A force is applied to a half-hollow punch rivet (3) by the punch during the punch rivet process based on the covered path. An attachment point of the punch rivet with the punch to a joint part (5) is determined, and a release point from the detected force/path data is determined. A release of the punch after the punch rivet process is identified during the release point. A rivet head end position and a compression dimension of the rivet are calculated. An independent claim is also included for a method for online-determination of embossing depth and rivet head end position of a full punch rivet.
